First Contact

The image depicts the first moments after Deep Impact's probe interfaced with comet Tempel 1. The illuminated -- and possibly incandescent -- debris is expanding from the impact site. The rough-hewn edges at the top and bottom of the flash are a result of light given off at impact saturating some of the pixels in the camera's imager. The pixels "bleed" excess electronic charge onto adjacent pixels in the same column.
